“…The asymmetric Michael addition constitutes one of the most powerful methods for the formation of new C–C and C–X bonds in organic synthesis. Especially after the development of organocatalysis, the aforesaid transformation has experienced exponential growth, with a large number of new catalysts exhibiting impressive results in terms of efficiency and selectivity . The Michael reaction between cyclohexanone and trans -β-nitrostyrene is a typical reaction for testing novel organocatalysts.…”

The synthesis of both trans- and cis-diastereomers of pyrrolidinine-thioxotetrahydropyrimidinone bearing either a fluorine or a hydroxyl group was accomplished. The new compounds were tested for their catalytic properties in a variety of asymmetric organic transformations and compared with the first generation catalyst. It was found that the new catalysts could efficiently catalyze the reactions in brine, without the use of organic solvent, and by employing an almost stoichiometric amount of reagents. Thus, the products were isolated by simple extractions, avoiding the use of chromatography in excellent yields, diastereoselectivities, and enantioselectivities.
